MOLD.

Specification of Letters Patent.

Application filed February 20, 1908.

Patented March so, 1909.

Serial No. 416,921.

Our invention relates to molds and particularly to that type of moldsused for forming concrete burial vaults.

The object of the invention is to provide a mold of this character whichmay be conveniently adjusted to differentsizes, which may be readilyassembled and taken apart, and particularly which will be adapted tocast both halves of the vault with slight alterations.

The further object of the invention will appear as the specificdescription which follows is read in connection with the accompa nyingdrawings in which- Flgure 1 1s a longitudinal sectlon of the moldassembled. Fig. 1s a transverse section showing the mold ready for usein molding the upper half of the vault. F 3 is a similar view showingthe mold ready for molding the lower'half of the vault. Fig. 4 is atransverse section of the top plate. Fig. 5 is a perspective view of thereducing plate. Fig. 6 is an elevation of the end plate used. Fig. 7 isa fragmentary section showing the reducing plate in position. Fig. 8 isa top plan view of an extension top for use wit the large size molds,and, Fig. 9 is a reduced sectional view of the vault in assembledposition.

Referring more especially to the drawings, 1 and 2 represent the innerand outer side members respectively, they being alike on both sides ofthe vault, and 3 and 4 represent the inner and outer end membersidentical for both ends also. The outer side members and the outer endmembers 1 and 3 are connected together by curved corner plates 5 havinga rabbcted offset 6 at either side thereof-to receive the side and endmembers so that the connecting edges will be flush. These corner plates5 are internally rabbeted as before explained and have rivets passingthrough them and engaging the side and end members so as to securethemtogether and form a substantially L-shaped wall. The opposite endsof the end members 3 are provided wlth a somewhat slmllar curved endplate 6 secured to the end plate by rivets 1 and having its innersurface rabbeted as at 8 to provide for flush surfaces as hereindescribed. The opposite side of the corner 'plate 6 in both instanceswhen it is connected to the end members is made perfectly'straight witha series of threaded bolt hole apertures 9 to be hereinafter described.

Secured to the corner members 6 by bolts 10 which enter the apertures 9of the corner member are adjusting plates ll rabbeted at 12 to receivethe corner member and provided at their opposite ends with a series ofholes to receive the bolts 13 which are carried by the connecting piece14 riveted to the side members 1. There are two of these adjust ingmembers 11, one for each side member 1 and two of the connecting members14. Each side member and the adjusting mem bers 11 are flared as at 15adjacent their bot-.

toms and are provided along their sides with reinforcing T irons 16 soas to prevent projecting under pressure. The side members 1 extend up aconsiderable distance above the inner side members 2 and inner endmembers 4 so as to provide a recess for the cement which enters andforms the bottom and top as'will hereinafter be described.

The inner side members 2 are connected with the end members 4 as are theouter side and end -mcmbers 1 and 3 with the exception that the cornerconnecting pieces 17 are externally rabbeted at 18 so as to present asmooth outer surface as distinguished from the smooth inner surface forthe outer side and end members. The opposite corner connecting pieces 19are similar to the corner connecting pieces 6 in the same respect thatthey have rabbeted portions 20 overlapped by the end pieces and rivetedthereto.

An adjusting member 21 is secured at each side to the corner connectingpieces 19 and to the inner side members 2 by bolts 22 which pass throughthe rabbeted portion 23 thereof and out into the smooth end of thecorner connecting pieces 19. The opposite end of the adjusting member 21is similarly rabbeted at 24 to receive the apertured. end of the sidemember 2. As these adjusting members are interchange able andreversible, it is necessary that a washeror strip be interposed betweenthe rabbeted projection and the inner side and end members extendperfectly straight from their top to their bottom but are similarlyprovided with T reinforcing irons 26 which are apertured at 27'toreceive a brace rod 28 having hook ends'29. Adjacent the upper end ofthe inner members we provide'an L su )porting iron 30 upon which thebottom p ate 31 may rest, and We also form holes in the horizontal armof the supporting member 30 so as to accommodate the hook 32 of a bracerod 33 rigidly secured to the curved top piece 34 as shown in Fig. 3.

The outside end plates 3 extend up some distance above the outside sideplates 1 on an arc of a circle so asto raise their u per (:Vd-gle to thetop of the cement linew 'ch be hereinafter explained. Adjacent the upperedge of the end pieces, we provide brackets 35 in which is removablysecured the tie. rod 36' extending from end to end of the mold frame.

In using the mold for reducing the size of the vault, the adjustingmembers, 21 and 11,- are dispensed with, and the members 37 are used in.their place. members are rabbeted on their side as at 38 to receive thecorner members, 6 and 19, and the side members 1 and 2. When thisreduction takes place, the side members 1 with. their rib 514, arepreferably substituted py the type of side members shown as 2 in Afterthe end and side members 1 and 3 have been secured together in the form'shown in Fig. -1 they are placed upon a support 38 which is providedwith spaced upstanding lugs 39 adapted to guide the side and end membersand prevent spreading thereof at their lower ends. Similar lugs 40 arearranged upon the support 38. so as to guide and prevent spreading ofthe inner side and end members 2.

At a central point between the lugs 39 and 40 we groove the support asat 41-so as to provide an extending rib 42 upon the upper half of thevault. The tie rods 28 are now placed in position and the reinforcingirons 26 on the top 34 are secured to the inner members by engaging thehook ends 32 of the rods. 33 with the apertures in the supporting plates'30. Cement is now inserted between the inner and outer side and endmembers and is troweled over the top so as to extend flush from theupper edge of the outer side and end members.

To form the bottom half of the moldwe insert a semi-cylindrical frame 43in the groove 41 of the support 38 and remove the top 34,

substituting therefor the flat top 31. Ce-[ These ment is poured in asbefore and the bottom is troweled along the line flush with the upperedge of the outer side and end members 1 and 3. This forms a fiat bottomand when the insert 43 isremoved a groove 44 is formed somewhat largerin internal diameter tha the external diameter of the rib 42.

When it is desired to seal the vault, cement ina plastic or liquid formis poured into the groove 44 and/the upper half placed upon the lowerhalf with the rib entering the groove and the liquid cement so as tolock the same. In molding the upper half we preferably insert handles 45to project above its curved top so that this section may be convenientlylowered into the grave. It will be clearly understood that the adjustingsection 47 is used only when a large sized vault is to be made and isused in between two sections of the top 34. When a small vault is to bemade, the section 47 is dispensed with as are also the members 21 and 11, which latter, have substituted therefor, the adjusting pieces 37.

And having thus described our said invention, what we claim as new anddesire to secure by U. S. Letters Patent is 1. A device of the classdescribed comprising an inner shell having end and side members, aplurality of corner members detachably connected with said end and sidemembers, an outer shell having end and side members and being spacedfrom the inner shell, insertion members for increasing the length ofsaid inner and outer shells, means to secure said insertion membersflush with the corner,

end and side members, and an interchangeable top for the same wherebythe' device may be used for upper or lower vault sections.

2. A device of the class described comprising an inner shell havingendvand side members, a plurality of corner members detachably connected tosaid side and end members, an outer shell having side and .end membersand beingspaced from the inner shell, a plurality of corner members, aplurality of in terchangeable members adapted to be connected flush withthe side .members and the corner members to change the size of the'innerand outer shells, an interchangeable'top whereby the mold may be usedfor the upper or lower sections of a vault and means coacting with thebase toform a groove in one section.

In testimony'whereof we have hereuntoset our hands in presence of twosubscribing witnesses.
